have a 450 gallon tank which is on the first floor and have a 300 gallon rubermaid sump in the basment underneath it. i need recomendations for pumps for a tank that size and take into consideration that the head hieght will be ten to 14 feet (meassured from pump to returns with probably one 90 degree turn)

i posted pics of the tank in the for sale as it may be upgraded to a slightly larger tank..that a whole nother story.

the idea is to have a pump working each side of the tanks and each has its own chiller..this will help in case one fails. so i am looking to install two pumps and two chillers one on each side of the tank/per overflow. the overflow and returns are designed that each will allow two returns and has an addition hole on the side of the return to use for a closed loop circulation.

i will attach a photo which shows it better.


also any comments on a good chiller. i already have a one third horse and am looking for a second one.

Your pic didn't work...Take a look at Dolphin pumps, ampmaster series.
Those pumps can handle lots of head.
Even with the ampmaster3000 and 13ft of head it'll pump 1200gph,
plus it'll only draw less then 1 amp. Two of these pump and you'll have over 2000gallon an hour.

With that much head I would probably consider one of the Iwaki's RLT pumps either a 55rlt or 70rlt that are made for presure. The only issue that I can see is that the size of the chillers will limit the amount of flow that you can have since chillers are limited to the flow through them. Even still you should be able to get 800-1000 gph depending on chiller to the tank per pump.
Unless you went with drop in chillers then you would have alot more room for bigger pumps like a pair of 100rlt's and get some good circultion.

I have a similar situation. I have my main tank upstairs and my sump in the basement. I use the AM3000 for the sump return, I am not pushing that much head though. I have my sump tank built up on a platform that I have to go up to steps to get 2 so my head pressure is less.

I would look at these pumps from Dolphin. Problem is they are energy hogs. But at your head you can still push 4700 gph with the 5000 series You may be able to incorporate this pump into both the return and skimmer or something else.

ltspd..the post above mentions that the amp master 3000 "draws less than one amp"

but you are of the opionn that they are energy hogs..are we talking about the same pump. also are these pumps a new series as i remember a post about bad pumps breaking down and a problem getting them fix under the warranty.

thanks for all your help

Chicago, the link I provided should have taken you to the 5000 series of dolphin pumps. They draw around 4-5 amps but move some serious water.
